HORIZONTAL-BAR EXERCISING APPARATUS.

SPECIFICATION forming part Of Letters Patent NO. 475,697', dated May 24,1892. Application led Ang-ust l0, 189]. Serial No. 402,297. (No model.)

To @ZZ whom t may concern:

Be it known that I, FREDERICK MEDART, a citizen of the United States,residing at St. Louis, in the State of Missourhhave invented certain newand useful Improvements in Ilorizontal-Bar Exercising Apparatus; andldohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to improvements in horizontal-bar exercisingapparatus for gymnasiums.

The object of the present improvements is to provide an improvedconstruction of such apparatus embodying the features of a firm andsubstantial attachment of the vertical posts or uprights to thegymnasium-floor in a manner to admit of their ready removal whenrequired, means for effecting an adjustment of the posts or uprights toa true Vertical position, and a simple and efficient construction of thesocket, whereby it can be readily adapted to the iioor of a gymnasium ina manner to admit of the shrinkage of the joists thereof beingcompensated for. I attain such objects by the construction andarrangement of parts illustrated in the accompanying drawings, in which-Figure l is a sectional elevation of a horizontal-bar exercisingapparatus constructed in accordance with my present invention; Fig. 2, ahorizontal section at line c ai; Eig. 3, a plan view ot' the bottom ofthe socket-casting and its connections; Fig. 4, a detail sectionalelevation of a modification.

Similar figures of reference indicate like parts in the different views.

Referring to the drawings, l represents one of the counterpart posts oruprights of the apparatus made of any suitable material and of anysuitable cross-section, preferably of channeled iron, in the form of aribbed letter H in cross-section, as shown in Fig 2, for the doublepurpose of affording ample strength with eXtreme lightness and at thesame time provide vertical channels to receive the ends to thehorizontal bar 2 in its dilferent vertical adjustments in use, suchhorizontal bar being secured to the required and 2.) The lower end ofeach post l is formed with a tapering end 5, which at its union with themain body of the post preferably forms a supporting shoulder or offsetG, as illustrated in Fig. l. The web of the post is formed with avertical series of apertures 6o '7 for the double purpose of lightnessand to afford means for the engagement of a pry or lever in removing thepost from its receivingsocket in the floor of the gymnasium. The

floor-socket may consist of a single casting,

as indicated in Fig. 4, this form being adaptede for a limited use ingymnasiums located on the ground fioorwhere the sockets will be requiredto be set in the earth in a suitable cement bedding. The more extendeduse of 7o my invention will, however, be in connection with the floorsof gymnasiu ms, and as so used the floor-socket will consist of an upperand lower member Sand 9, secured, respectively,

in a recess in the flooring and to the bottom of the floor-joists, andsubstantially connected together by tie-bolts l0, as shown. The uppersocket member 8V is formed with a surface recess ll of a somewhatgreater area than that of the post, so as to readily receive lSo thehorizontallyadj ustable bolts l2 in the post and form an abutmentfor thesame as they are screwed in or out to effect the proper verticaladjustment of the post, as well as the securing ofthe same solidly in anerect position. The

lower socket is provided with rabbets 13, that enter gains cut in thejoists, as shown, so as to better retain its proper position, and isprovided with a downwardly-extending sleeve 14, through which the seriesof radial hori- 9o zontally-arran ged ad justing-screws 15 pass toengage and adjust the eXtreme lower en'd of the post. Y

The means of adjustment described is a very valuable feature ofconstruction in that it affords means for adjustment, when from anyaccidental causes-such as shrinkage of the floorandjoists, &c.-anadjustment of the posts or uprights is necessitated. Such means are not,however, absolutely requisite and roo dass? may be dispensed with and avery useful construction still provided.

Having thus fully described my said invention, what I claim as new, anddesire to secure by Letters Patent, is

1. In a horizontal-bar exercising apparatus for gymnasiums, thecombination ofa postl or upright l, having horizontal screws l2, andthefloorsoeket provided with a surface recess 11 to receive the same,substantially as set forth.

lower end of the post or upright, substantially as set forth.

L In a horizontal-bar exercising apparatus' for gymnasiums, thecombination, with the Hoor-socket, of a post or upright having a ribbedletter H formation, the flan gesof which are formed with a verticalseries of holes 4 for effecting an adjustment of the end ofthehorizontal bar, substantially as set forth.

5. In ahorizontal-bar exercising apparatus for gymnasiums, thecombination, with the floor-socket, of a post or upright having a ribbedletter H formation, the Web of which is formed with a vertical series ofapertures 7, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

FREDERICK MEDART.
